Happiness Measure(s) and Distributional Findings
- Full text:
Selfreport on single question:
… feel happy most of the time.. (full text not reported)
- Author's label:
- All respondents that were not able to answer self-report questions because of severe cognitive decline were excluded from the sample.
The publication reports an analysis using a ' happiness factor' consisting of 2 more measures which do not fit the criteria for inclusion in the WDH. Hence the results obtained with that measure are not included here.
